There really is nothing special about Relacore.
I will tell you what I've learned from reading about fat loss and also losing over 100 lbs myself. Most of my weight loss has been from my "core" area which is basically my stomach. If you are morbidly obese and lose weight, you will most likely experience the same thing. The reasoning is that after a certain point in weight gain, our body starts to store fat around our midsection more than other sections. This fat is considered toxic fat because it is around our organs. Our body wants to get rid of this fat the quickest. So once you start to lose weight, you lose it around your midsection. It is why they advertise that it is only for those that are extremely overweight because this phenomenon doesn't happen to those that have 20-30 lbs to lose.
As for men, most of their fat is already around their belly area so of course if they lose weight, they will lose it around their midsection. Men are designed to store fat in their midsection while women are designed to hold it in the midsection and hips.
Anyway, save your money
